Wetasin-dadlp Dispersing Agent, Classification : Textile

Description :

Wetasin- DADLP is a very efficient dispersing cum leveling agent designed for application in dyeing of Polyester with disperse dyes.

Advantages

§ Enhanced ‘migration’ of Disperse      

    dyes to get level dyeing

§ Excellent dispersing power

§ Controls exhaustion rate and ensure    

    level dyeings even in rapid dyeing

    machine

§ Very effective in sensitive colours

    where fabric tends to dye unevenly

§ No retarding action on dyeing

§ Gives brighter dyeing

§ Features

    APEO/NPEO free

§ Bio-degradable

N.B. Reduction Clearing Treatment

Wetasin-VL                                                1 g/l

NaOH (Sodium Hydroxide, solid)     2 g/l

Hydros (Sodium Hydrosulphite)       2 g/l

Treat the goods for 15 to 20 minutes at 70 to 80oC to achieve optimum fastness and clarity of shade

Wetasin - DA-DLP used as dispersing and levelling agent in dyeing polyester

Wetasin - DA-DLP is suitable for use on all types of high temperature dyeing machinery. After scouring the goods where necessary, the dye bath is set with fresh water and temperature raised to 60ºC

 Meanwhile, Wetasin - DA-DLP is pre-diluted by adding the product to 4-5 times its own volume of warm water.

Wetasin - DA-DLP                                                0.5 to 1.0 g/l

Wetasin- HTS (sequestering agent)             0.5 g/l

Acetic acid or Acid buffer Adjust pH to       4.5 to 5.5

Disperse dye                                                           x% owf

Add pre-diluted Wetasin-DA-DLP to the bath together with other chemicals required (sequestering agent, acid/acid buffer) and circulate. Adjust to pH 4.5 to 5.5.

Add well-dispersed dyestuff, preferably through a sieve or filter.

Raise temperature from 60ºC to maximum dyeing temperature (130- 135 o C) at desired temperature gradient. Rapid rates of rise of 2 to 4 deg C per minute are possible. Run 30 to 60 minutes. Cool to temperature at which the liquor can be safely drained without causing creasing, then rinse or back-scour/reduction clear as necessary.

Wetasin-DA-DLP used as stripping agent or re-levelling of faulty dyeing

Wetasin- DA-DLP can be used to correct unlevel dyeing or to reduce the depth of dyeing dyed too heavily. Treat for 30 to 60 minutes with:

Wetasin- DA-DLP 2 to 5 g/l

 At maximum dyeing temperature, this treatment will hold the removed dyes in the bath. If shading corrections are necessary, these should be carried out after replacing all or most of the bath. Otherwise, such high concentrations of Wetasin- DA-DLP will not permit good exhaustion

Stripping or re-levelling treatments should be followed by thorough rinsing and reduction clearing to ensure maximum fastness.
